An electrooptical converter comprising sequentially located on the optical axis: at least one optical lighter, a transparent support or M transparent supports, each in the form of at least one plan-parallel plate or at least one prism of full internal reflection, at least one line modulator, at least one visualizer, a perception device, and at least one control device, wherein each line modulator comprises a transparent electroconducting layer applied to the transparent support, the electroconducting layer being covered with a transparent gel-like layer, and a system of i parallel ribbon control electrodes and ground electrodes, arranged in one plane on a second support corresponding to each of line modulators and located with a gap above the transparent gel-like layer and electrically connected with the corresponding control device, wherein each transparent support together with the corresponding at least one modulator forms a line element; while the optical lighter consists of a lengthy light source and a lighting convertible lens sequentially located on the optical axis, and the visualizer includes a Fourier-objective and a visualizing diaphragm sequentially located on the optical axis; while the light source is pulse or continuous, and the frequency of light pulses recurrence is equal to the line frequency of the image; the ribbon control electrodes are electrically connected to the periodic structure of control teeth, and the ground electrodes are electrically connected to the periodic structure of ground teeth, for each line pixel the teeth together with the corresponding electrodes look like two conducting combs isolated from each other, while the combs' teeth are located in parallel to the lengthy light source, while the location period of the pairs of the control teeth and ground teeth λ teeth is calculated from the relation: λ teeth ≤√2 λ light /α div., wherein λ light is a wave length of the lengthy light source and α div. (in radians) is a divergence of the radiation of the light source in a direction perpendicular to the combs' teeth. |
